OptimizePress includes a very small, unobtrusive logo in the bottom right corner, turned on by default, that allows OptimizePress Affiliates to include their affiliate link so they can promote OptimizePress on every page they create.
If you would like to turn off this feature, first head over to your WordPress Dashboard, and then click on “OptimizePress3” and then “Settings”
On the Settings screen, click on the “Affiliates” tab, simply toggle this to the “Off” setting (by clicking on the toggle switch), and then save your settings.
Once you save your settings, you should clear your site and browser cache and the logo will not appear any longer.
Alternatively you may also add your affiliate link or any link you choose (such as an Affiliate offer page).
